No More Learning

When I           a food which you admire;
You blame and say, I never ought to tire;
You do the very same; in truth, my friend,
No mark of folly 'tis, you may depend,
In lord or squire, or citizen or clown,
To change the bread that's white for bit of brown:
With more experience, you'll with me agree,--
My motto ever is--VARIETY.
